help me.. thanks..
F = ma.. in equilibrium,our body's weight is forcing downward. and there is a reaction force(same value and upward)= Newton's third law.when the lift is moving upward, the force acting upward increases. and that force also has a reaction force acting downward. this reaction force will be add to...
